Merlin M102 Infrared Safety Senors
Infrared safety sensor beams for swing and sliding gates.
Merlin M102 sensor beams will only function correctly on
Merlin’s G model openers.
They will work no matter which way their wiring is connected.
M102 sensor beams send a coded signal down their power
supply wiring, so only a Merlin opener can provide the correct
power supply and decode the state of the beams correctly.
